Lydia Deetz
Lydia Deetz - a goth girl in her preteens at the start of the series, (she was in the seventh grade) and early teens later in the series, (at one point she expressly states that she is 14). Lydia is established as being a creative, bright, sharp, yet eccentric young girl, but otherwise Lydia's unique outlook on life makes her stand out from most of the other school-girls, which leaves her feeling out of place and alone in the real world, finding it difficult to fit in well with most of her classmates—leading her to frequently visit and seek out reassurence with her closest best friend, Beetlejuice, in the Neitherworld, where she is accepted and loved for who she is as a person.
Lydia is an amateur, but nonetheless, talented photographer, entomologist, seamstress, and sketch artist with an innate affinity and love for all things gross, scary, weird and macabre, and who celebrates all that is 'strange and unusual'. Despite her love of all things 'strange and unusual', Lydia is also a positive, well-mannered, friendly and patient girl, (being best friends with Beetlejuice is a testament towards Lydia's saint-like patience.) And aside from also being emotionally mature for her age (given what her best friend and her parents are like), Lydia can be accredited as being very responsible for a girl in her age group. Lydia is also shown to be a naturalist, shown to feel very strongly about environmental issues, (in Spooky Tree Lydia cut school and chained herself to a tree in protest of the workmen who were about to chop it down). She has also shown that she is extremely gifted with anything mechanical, and understands a lot about cars (she knew what to do to build Doomie, while Beetlejuice did not know very much, such as what a carburetor is).
In the series, Lydia attends "Miss Shannon's School for Girls" and is in seventh grade. Lydia is Beetlejuice's best friend; in the events of the pilot episode, Critter Sitters, both she and Beetlejuice have already known each other for a year, as they are celebrating their first anniversary of friendship. Beetlejuice frequently addresses her as "Lyds" or "Babes" rather than "Lydia" though he does use her full name from time to time, like when he is scared, amused, or worried about her. For example:in "Worm Welcome" when Beetlejuice found out that "Worm Your Way" deodorant, causes baby Sandworms to go crazy, he was scared Lydia would be eaten by the baby Sandworm thus in turn, makes himself shout her name. Lydia knows how to summon Beetlejuice to her presence, or make her own way to his: by calling his name aloud three times. (Occasionally she is shown making use of a longer, more elaborate ritual to bring him out of the Neitherworld or send herself into it, but that seems not to be a necessity.) Unlike Beetlejuice himself, Lydia is almost universally loved by the Neitherworld cast of the show.
In the pilot episode, Critter Sitters, she is shown summoning him through the longer ritual; as part of the ritual, the colour of her clothing changes, possibly merely by her choice. (Her invariable Neitherworld costume—unless she is in disguise—is a full-length red spiderweb-patterned poncho worn over a black, form-fitting body suit.) She is not the only person capable of summoning Beetlejuice—apparently the calling of his name would work for anyone (in one episode, Claire Brewster summons him accidentally)--but Lydia is the only person he will heed (because she is his friend, not because she summons him). Having found herself a kindred spirit in Beetlejuice, Lydia looks up to Beetlejuice in certain ways; admiring his outrageous sense of humour, as she would constantly be seen laughing at his jokes or gags. In one episode Beetlejuice lent Lydia his funny bone so she could be funny as part of a school show. But without his funny bone, Beetlejuice became much more serious and normal, this change in him even disappoints Jacques and Ginger. When Beetlejuice gets his funny bone back however, he becomes his ab-normal self again much to Lydia's delight as she hugs him. In some respects Lydia sometimes has been seen virtually parenting Beetlejuice. It is frequently made clear that Beetlejuice's dedication to her is a source of Lydia's own self-confidence.
Meanwhile, any who might conceivably threaten their relationship (such as Prince Vince) are the objects of Beetlejuice's profound jealousy and resentment. In one episode, we learn that Beetlejuice actually has a working shrine to Lydia in his mind. Lydia never shows any romantic interest in anyone else except Prince Vince, and that quickly turns into a straight-out friendship. She's hugged Beetlejuice a few times (if in a sisterly manner), and frequently goes on dates with him (such as to movies)--always, of course, in the Neitherworld. Also, when she was inside Beetlejuice's head, she gave a donation towards the maintenance of his shrine to her. Her main hobbies, aside from photographing every sort of strange thing, hanging out with Beetlejuice, drawing, includes watching horror movies and customising dolls into famous horror movie characters and monsters, reading literary classics such the collective works of writers such as Edgar Allan Poe and Stephen King and others.
